Obviously to "WDW" varies with where you are headed ie., which park, resort, etc. We stayed at OP in late August over Labor Day and again in early December. Traffic was not too heavy at either time of the year. I would be surprised if it takes you over 20 minutes to get to any park from there. We were at VV in late January and I would say the time from the parking lot to the parking lot of one of the parks was between 12 to 15 minutes. If you use the 535/536 roads to get to the Disney parks from OP your times will be much better than driving up 192 the entire way. I would not switch resorts just for the travel time issue. The OP has to be much cheaper than VV at this time of the year.
